Referring now-.more particularly to the drawings-,.-. the numeral 10 -indicates the shankof-a connecting rod, 11Y theflower. vend bearing thereofwliieh is formed in an upper sec-tion, 12 Yintegral with the shank and 'azlower section 13 bolted-'on otherwise secured. thereto, ,the lower. end.- bearing being adapted, yas vis well .-lnow'n, for: the reception of-'the cranltfshaft. of the. engine.

rality of minute openings 20. In conjunction with the pocket I provide a false pocket 21, the lower end of which is designed to engage against the upper end of the pipe 18 to be supported thereby. This false pocket 21 is shaped to closely fit against the walls of the pocket 14 at the upper' end thereof and is provided at its lower end with an opening 22 aording access to the pocket 14. Any suitable means-may be provided for maintaining the false pocket 21 in position. In the present instance I have disclosed this pocket as being provided with an upward extension 23 having at its end a ieXible tongue 24 which may be engaged in a notch 25 formed in the wall of the connecting rod shank.

As hereinbefore stated, one of the pockets 14 may be formed at each side of the connecting rod and the pipes leading from the pocket 14 will connect with oil grooves 2G formed in the bearing face. It will be seen that oil entering the false pockets 21 will pass through the openings 22 in the bottom thereof into the pockets 14 and that escape from the pockets 14 will be prevented by the false pocket 21, so that the oil is retained in the pockets 14 until such time that it is employed. The screen formed by the minute apertures of the pipe 18 will prevent any dirt which may enter the pockets from passing to the bearings and accordingly only clean oil will be delivered thereto. IVhen repairs are made to the engines the r false pockets 21 may be removed and the pockets 14 cleansed to remove. collected dirt and sediment. The-amount of oil which will collect in the pockets 14 will be su'llicient to lubrica-te the same for a considerable period and accordingly damage which otherwise might result to the engine during traveling on long hills will be avoided. Furthermore, if the oil is allowed to attain too low a level in the sump the lubrication will be provided for the bearings for a considerable period.

It will, of course, be obvious that the ordinary connecting rod, while splashing a considerable amount of oil, will not splash sufficient oil to keep the pockets of the type described filled at all times and I accordingly provide upon the lower bearing section 13 of the bearing a depending flange 27, which upon rotation of the engine will dip into the oil of the sump and throw the same against the walls of the cylinder from which it may drip to engage in the pockets 14. I further provide from the side edges of the flange 27 other flanges 28 combining with the flange 27 to form upon the lower surface of the bearing a scoop. It will be obvious that oil striking the flange 27 will have a tendency to spread and move uprIhese side flanges, therefore, prevent the loss of a considerable amount of oil which would otherwise be splashed and in addition cause the oil to be forced against the lower surface of the lower bearing section 13. Through this bearing section I form an opening 29, which opening communicates with a longitudinal groove 30 formed in the bearing surface of the lower bearing section and a portion of oil forced against the lower face thereof will accordingly be delivered through such groove to the connecting rod. From the foregoing it will be obvious that by the use of a bearing constructed in accordance with my invention, burning of the bearings will be to a gre-at extent eliminated and a constant supply of oil to the bearing practically assured. It will furthermore be obvious that the construction hereinbefore set forth is capable of a certain range of change and modification without in any manner departing from the spirit of my invention and I accordingly do not limit myself to such specilic structure except as hereinafter claimed.

I claim:

l. The combination with a connecting rod having a bearing, the rod having an oil pocket formed therein and communicating with the bearing, the pocket having an open upper end, of a false pocket disposed. within said pocket and closing the upper end thereof, said false pocket having an opening formed-in the lower end thereof and communicating with the first named pocket.

2. The combination with a connecting rod having a bearing, the rod having an oil pocket formed therein, the oil pocket having an open upper end, of a tube carried by the bearing and communicating with'the bearing surface thereof having its end portion extending into the oil pocket and provided with a plurality of minute openings permitting oil from the pocket to pass therethrough to the bearing.

3. rl`he combination with a connecting rod having a bearing, the rod having an oil pocket formed therein, the oil pocket having an open upper end, of a tube carried by the bearing and communicating with the bearing surface thereof having its end portion extending into the oil pocket and provided with a plurality of minute openings I permitting oil from the pocket to pass therethrough to the bearing, the upper Vend of said tube terminating short of the upper end of `the pocket and being closed.

4. The combination with a connecting rod having a bearing, the rod having an oil pocket formed therein, the oil pocket having an open upper end, of a tube carried by the bearing and communicating with the bearing surface thereof and having its end portion extending into the oil pocket and provided with a plurality of minute openings permitting oil from the pocket to pass therethrough to the bearing, the upper end of said tube terminating short of the upper end of the pocket and being closed, and a false pocket disposed within the upper end of said pocket to close the upper end. thereof, said false pocket having an opening formed in the lower end thereof permitting oil to pass therefrom to the yfirst named pocket.

5. The combination with a connecting rod having a bearing, the rod having an oil pocket formed therein, the oil pocket having an open upper end, of a tube carried by the bearing and communicating with .the bearing surface thereof and having its end portion extending into the oil pocket and provided with a plurality of minute openings permitting oil from the pocket to pass therethrough to the bearing, the upper end of said tube terminating short of the upper end ofthe pocket and being closed, and a false pocket disposed within the upper end of` said pocket to close the upper end thereof, said false pocket having an opening formed in the lower end thereof permitting oil to pass therefrom to the first named pocket, and means carried by said false pocket and engaging the connecting rod to maintain said false pocket in position in the first named pocket.

G. A connecting rod having a bearing, the rod having upon its outer faceV an oil pocket having an open upper end formed therein, the lower end of the pocket com municating with the bearing, and removable means at the upper end of the pocket forming an auxiliary pocket for the reception of oil, said removable means closing the upper end of the main pocket and being provided with an opening communicating with thev pocket. l

7. The combination with a connecting rod having a bearing and provided at its sides with outstanding ianges, of a member connecting said anges to one another and connected at its lower end to the bearing and combining therewith to form upon the side of the connecting rod an oil pocket the lower end of which is formed by the bearing, the bearing having an opening formed therein for passage of oil from the pocket to the bearing face thereof, and a false pocket disposed within said pocket and closing the upper end thereof, said false pocket having an opening formed in the lower end thereof and communicating with the first named pocket. l

8. A connecting rod having a bearing, the rod having upon its outer face an oil pocket having an open upper end formed therein, the lower end of the pocket communicating withr the bearing, and a baffle between the upper and lower ends of the pocket preventing splashing of oil from the pocket and permitting transmission of oil from the upper end of the pocket to the lower end thereof.

9. A connecting rod having a bearing, the rod having upon its outer face an oil pocket having an open upper end formed therein, the vlower end of the pocket communicating with the bearing, and a baflie between the upper and lower ends of the pocket prevent ing splashing of oil from the pocket and permitting transmission of oil from the upper end of the pocket to the lower end thereof, said baffle being removable from the pocket.

In testimony whereof I hereunto affix my signature.
